901:5-3-13
Systems mounted on farm equipment for the delivery of ammonia.

(1)
A suitable "stop" or
"stops" shall be mounted on farm equipment or on the container in such a way
that the container shall not be dislodged from its mounting due to the farm
equipment coming to a sudden stop. Back slippage shall also be prevented by
proper methods;

(2)
A suitable
"hold-down" device shall be provided which will anchor the container to the
farm equipment at one or more places on each side of the container;

(3)
When containers are mounted on four-wheel
farm equipment, care shall be taken to insure that the weight is distributed
evenly over both axles;

(4)
When
the cradle and the container are not welded together, suitable material shall
be used between them to eliminate metal-to-metal friction.

(1)
All containers shall be equipped with a
fixed maximum liquid level gage;

(2)
All containers with a capacity exceeding
two hundred fifty gallons shall be equipped with a pressure gage having a dial
graduated from zero to four hundred psig;

(3)
The filling connection shall be fitted
with combination back-pressure check valve and excess flow valve; one double or
two single back-pressure check valves; or a positive shut-off valve in
conjunction with either an internal back-pressure check valve or an internal
excess flow valve;

(4)
All
containers with a capacity exceeding two hundred fifty gallons shall be
equipped for spray loading or with an approved vapor return valve;

(5)
All vapor and liquid connections, except
safety relief valves and those specifically exempt in rule
901:5-3-03 of the
Administrative Code, shall be equipped with approved excess flow valves or may
be fitted with quick-closing internal valves which, except during operating
periods, shall remain closed;

(6)
Fittings shall be protected from physical damage by means of a rigid guard
designed to withstand static loading in any direction equal to twice the weight
of the container and lading using a safety factor of two based upon the
ultimate strength of the material used. If the guard is fully enclosed, the
safety relief valves shall be properly vented through the guard;

(7)
If a liquid withdrawal line is installed
in the bottom of a container, the connections thereto, including hose, shall
not be lower than the lowest horizontal edge of the farm equipment axle;

(8)
Provision shall be made to
secure both ends of the hose while in transit.

(1)
Any farm equipment shall be
securely attached to the vehicle drawing it by means of drawbars supplemented
by suitable safety chains;

(2)
Any
farm equipment shall be constructed so that it will follow substantially in the
path of the towing vehicle and will prevent the towed farm wagon from slipping
or swerving dangerously from side to side and shall display a slow moving
vehicle emblem;

(3)
Each piece of
farm equipment transporting anyhydrous ammonia shall carry a container of at
least five gallons of water and shall be equipped with rubber gloves and either
a full face mask, or a pair of tight-fitting goggles, or one full face shield.
The driver shall be instructed in their use and the proper action to take to
provide for his safety.
